This patent application is a division of my patent application SerialNo. 475,929, filed February 15,1943, now Patent No. 2,389,965.

This invention'relates to a method of making clips that are used to holdsuspended articles in position. f

The principal object is to provide an improved method of assembling andfastening the. base and shank of a said clip together, that is simple,economical to accomplish and most durable.

The foregoing and other objects which will appear as the nature of theinvention is better understood, may be accomplished bya method such asis disclosed by the specification. The. nature of the invention is suchas to render it susceptible to various changes and modifications, and,therei'o're, I am not to be limited to said disclosure; but am entitledto all such changes therefrom as fall within the scope of my claims.

In the drawings:

Figure 1 is a perspective view of the base and shank of my clip beforethey are assembled and interlocked. v

Figure 2 is a front elevational view, partly in section, showing theshank tongue in position ready to be forced into locking engagement withthe base of my clip by two dies.

Figure 3 is 'a front elevational view, partly in section, showing theshank tongue interlocked with the clip base, upon completion of'thefinal step in my method. 2

Figure 4 is a persp tiv clip. r Figure 5 is a plan view of the femaledieused in the aforesaid method. I

First I will describe the parts of my clip, which, as illustrated, hasa, flat base l0. Two slits .l I spaced apart are cut therein betweenwhich a portion of said base is thereby forced outwardly view or mycompleted to provide what I call an offset portion I2. .This.

leaves a space I3 directly opposite said offset which space is laterallyopposite adjoining portions of said base. When used to hold insulatingmaterial in place next to a ceiling or wall said base usually has cementapplied to it thus adhesively holding it to said wall or ceiling. Thebase has relatively large surface area to 1 provide a strong adhesiveJoint between saidbase and said ceiling wall.

Attached to said base I is a'shank "having at one end extremity a tongueportion I! extending at a right angle. The other end extremity has aslot it which extends about half the length of said shank. On each sideof said slot It fingers l1 arethereby formed. When my clip is in posiacam. for. art-14a) tion of use, said fingers I! {extending through theinsulation and are bent over at a rightangle to lie approximately flatagainst said insulation.-

In practicing my method said locking tongue l is inserted intosaidspace. l3 opposite said offset portion l2, andextends beyond saidspace l3 and overlaps aportion of said base 10. To interlock said tonguel5 with said base I0 I provide a female die especially shaped for thepurpose, having a bulge 2i narrower than, but which fits against saidoffset portion I2 forthe length thereof. .A flat male or hammer die 22strikes against a portion of said base Ill with such force that the partof said offset portion I! in contact with said.

female die bulge 2| is deformed and driven inwardly against said basetongue l5 which deforms and forces part of said tongue to enter saidspace li'thereby interlocking said tongue and base. It will be noted inFigure 3 of the drawings that an intermediate portion of said offsetportion I2 is sunk inwardly as a result of the force of the hammerlikeblow to thereby form a longitudinally extending channel therein and thisis likewise I true of said tongue,

' What I claim is:

1. The method of making a clip having a shank embodying a flat tongue atone extremity extending at substantially a right angle to the adjoiningportion, and having a base having two slits in an intermediate portiontherein spaced apart. said base having an offset portion between saidtwo slits thereby leaving an adjoining space between said ofiset andadjacent portions of said base, inserting said shank tongue into saidspace and holdingv a. female diehaving a bulge therein thatis of lesswidth than said oflset portion with said bulge bearing against alaterally intermediate part of said offset portion while forciblystriking a surface of said base towards said off- 1 set portion andtongue to thereby distort said ofiset portion and said tongue andinterlock them and cause a portion of said tongue to enter that part ofsaid space that is laterally opposite adjoining portions of said baseand force a portion of said tongue substantially'level with the surfaceof said base that was struck.

2. The method of making a clip having a shank embodying a tongue at oneextremity and a base having two slits therein spaced apart, said basehaving an offset portion between saidtwo slits thereby leaving anadjoining space between said offset and adjoining portions of said base,inserting said shank tongue into said space and stationarily holding afemale die against said offset portion while strikinga portion of saidbase forcibly to thereby distort said oflset portion into encasementwith said tongue and simultaneously substantially filling that saidspace with a portlon at said tonsue. v
